To figure out why your electric bill is "so high", the first thing you need to do is to
figure out what's normal. If your bill has spiked recently that's easy: Just look at your old bills and see how much your usage has gone up. Look only at the amount of electricity you used in
kWh. Don't look at the cost, because the cost could have gone up for other reasons, such as an increase in the price of electricity itself.
If your kWh usage is similar but the cost is now higher, then the answer as to why is on your bill. Maybe the price of electricity went up, or maybe your utility company has
demand charges, or maybe you're being charged for some other city services besides electricity.
Maybe your bill hasn't gone up but you just think it's always been too high? In that case the first thing you can do is to compare your usage to what's normal. A typical American family uses 850 kWh per month, as we see on the
how much electricity costs page. If you're anywhere near that with a 3-person household you're normal. Normal doesn't mean good, though, since most people waste lots of energy. Personally, I use only about 99 kWh per month.
Let's say you still think there's an unknown reason why your electrical usage has been so high recently. In that case the next thing you should do is to make sure the bill you received is accurate. Once I got a bill that said I used 2617 kWh, when I normally use only 100. A quick look at the meter showed that they read the meter wrong. My bill said the starting and ending meter reads were 18,441 and 21,058. But when I got my bill checked my meter it was only at 18,567, so clearly my meter hadn't really ended on 21,058 the previous month. The utility quickly refunded the $195 they overcharged me.(ලංකාවෙ නං ආපහු දෙන්නෙ නෑ)
If your meter matches your bill, meaning you weren't overcharged,
your next step is to verify that your meter isn't running gratuitously. Shut off all the breakers and see if the meter is still spinning. If it is then your meter is broken. It's highly unusual, but it's possible. In that case pay an electrician $40-50 to come out to confirm that and to sign a statement to that effect so you have proof when you go battle your electric company to get back the money they overcharged you. Videotaping it wouldn't hurt, either.(ලංකාවේ නෙවෙයි හොඳේ)
But your meter is probably not broken. Assuming it isn't then the next step is to
make sure the meter doesn't run when everything is turned off. That way when we start turning appliances back on to measure their use, we can be confident that we're measuring only that appliance and not some other appliance as well. To do this turn off every light in the apartment and physically unplug every appliance from the wall (simply turning it off isn't good enough for some appliances. The water heater might be hard-wired without a plug and in that case you'll have to just make sure it's turned off. And of course you can't unplug a central AC system so just turn it off. Once everything is turned off and unplugged, flip the breakers back on one at a time and verify that the meter still doesn't spin. If the meter still spins and you're 100% certain you've turned off every light and physically unplugged every device, then try each breaker one at a time to see if multiple breakers cause the meter to spin or just one of them does. Try each breaker that makes the meter spin and calculate how much electricity each breaker is using by
using the meter timing method. Each 100 watts that is running continuously uses about 73 kWh per month. If you're paying 10¢ per kWh, it costs you $7.30.
You probably didn't find any smoking gun in that last step. So now we'll proceed to
measure how much electricity your stuff uses. As we cover on our
how to measure electricity use page, you can either use a $35 plug-in watt-hour meter, or you can use the meter timing method. The latter is free but it's a
lot more cumbersome. If you value your time and your sanity you'll get a cheap watt-hour meter. Use your meter to measure the electricity used by the devices in your home. You can then use our page to figure out
how much that usage costs you. Likely you'll find that there is no mystery, that your bill is high simply because you're using a lot of electricity.
At that point all you need to do is to start using less electricity. Go to the
how much your stuff uses page to see what the energy hogs are in a typical home, and then use the tips on this site to reduce your electrical use. You can do it. Remember, I use only about 99 kWh/mo.
